Antioxidants

Description

Brand: SONGWON

Country of manufacture: South Korea

Grade: 168-1010

Application:

Oxidation is one of the degradation factors of many polymers and plastics during production and during the consumption cycle. As a result, today the producers of polymer products must use antioxidant polymer additives in order to improve the quality of their products and also prevent oxidation and destruction of their products.

Antioxidants Antioxidants

Objects made of polymers have the possibility of oxidative damage and their service life is shortened. Anionic oxide destruction can lead to:

color change
Loss of clarity
Loss of tensile strength
Loss of impact strength
decrease in other properties of polymers.
AO stands for antioxidant.

In general, polymer materials are sensitive to oxygen and oxidize, including:

Natural polymers
Synthetic polymers
The resistance of different polymers to oxidation is very different:

High resistance: polystyrene and polymethyl methacrylate
Low resistance: unsaturated polymers and elastomers
Methods to prevent oxidation of polymers:

Modification of polymer structure: copolymerization
Covering end groups (mostly for polyesters)
Physical stabilization by orienting the polymer (PET bottles)
Addition of AO: the most common method of stabilization of polymers

Definition of AO:

Substances that have a special chemical structure that show their effect in low concentrations and because they react faster with free radicals than the polymer, they prevent the oxidation of the polymer.

Some properties that AO should have:

It is in powder form and melts easily (proper distribution).
Do not cause color change.
Stop the destruction process by copper, magnesium and other metals.
not toxic
Do not run away.
Oxidation of polymers:

The oxidative degradation process is due to the reaction of free radicals with polymers, which includes 4 stages:

start stage
Release stage
Self-catalytic stage
The final stage
Irganox 1010 antioxidant can be used in polyolefins such as polyethylene, polypropylene, polybutene and olefinic copolymers such as ethylene-vinyl acetate copolymers. It is also recommended that this stabilizer be used in the processing of polymers such as polyesters, polyamides, and polyurethanes, polyesters, PVC, styrene homo and copolymers, ABS, elastomers such as: butyl rubber, SBS, SEBS, EPM, EPDM, as well as other synthetic rubbers and adhesives and resins. Use synthetic and natural glue and other organic material base.

Plastic products that mostly contain antioxidant additives are:

All types of pipes and fittings used in the building and construction industry

Polyethylene films (PE films) were used in various applications from manufacturing to food packaging

Products and films made of polypropylene (PP)
